I am using remote data base installed on different machine. DB Manager works OK and sees all databases. I checked also databases hosted locally and shp2pgsql.exe is located in the place you pointed. Unfortunately loading still do not work

A very basic workaround would be to open postgis and shapefile layers in qgis, select all objects from shapefile layer by rectangle, Edit->Copy Objects, make postgis layer editable and Edit->Insert objects from the menu bar.
